TNotifyEvent - Eigenschaft, Aktion, oder was?

[Luckie]

In der Kürze liegt die Würze:

Delphi-Quellcode:

type
  TForm1 = class(TForm)
    procedure FormCreate(Sender: TObject);
  private
    { Private-Deklarationen }
    procedure MyBtnClick(Sender: TObject);
  public
    { Public-Deklarationen }
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}

procedure TForm1.MyBtnClick(Sender: TObject);
begin
  ShowMessage('foobar');
end;

procedure TForm1.FormCreate(Sender: TObject);
var
  MyButton: TButton;
begin
  MyButton := TButton.Create(Form1);
  MyButton.Parent := Form1;
  MyButton.OnClick := MyBtnClick; 
end;
